[0003] 2. Description of the Related Art

[0004] In the enclosure of a typical personal computer, there are generally two disk drive brackets mounted therein. Usually, a variety of disk drives are received in the disk drive brackets, which are then secured into the enclosure. There are many ways to secure the disk drive brackets in the enclosure. One way is by using screws. A pair of joining edges is formed on opposite sides of a bottom of a lower disk drive bracket. Fixing holes are defined in the joining edges. The lower disk drive bracket is secured to a bottom of an upper disk drive bracket by screws. However, this way of securing the disk drive brackets is unduly painstaking and time-consuming. Disassembly of the disk drive brackets is similarly painstaking and time-consuming.

[0005] Another way to secure the disk drive brackets in the enclosure is by using hooks. An example of a pertinent mounting apparatus for disk drive devices is disclosed in Taiwan patent application No. 81205427. One side of a first disk drive bracket has a plurality of L-shaped flanges and a plurality of L-shaped projections. A corresponding side of a second disk drive bracket has a plurality of L-shaped projections and a plurality of L-shaped flanges, respectively corresponding to the L-shaped flanges and L-shaped projections of the first disk drive bracket. Each flange fastens to the corresponding projection. Thus the second disk drive bracket is secured to the first disk drive bracket. This mounting apparatus does not need screws. However, the disk drive brackets must be assembled by hand inside the computer enclosure. Thus makes the assembly operation inconvenient, and increases the risk of accidental damage to other components such as sensitive electronic components inside the computer enclosure.

[0006] Thus an improved mounting apparatus which overcomes the above-mentioned problems is desired.

[0007] Accordingly, an object of the present invention is to provide a mounting apparatus which readily secures data storages devices therein and allows convenient removal of the data storage devices therefrom.

[0008] To achieve the above-mentioned object, a mounting apparatus comprises a chassis, a fixing member and a drive bracket. The chassis comprises a front panel defining an opening and a through hole adjacent to the opening therein. The fixing member comprises a main body mounted to the chassis. The main body comprises a fixing part formed upwardly at a front portion, an operation part extending forwardly corresponding to the through hole, and an elastic hook extending rearwardly therefrom at a rear portion. The drive bracket holding a plurality of data storage devices comprises a mounting wall. The mounting wall comprises a stop formed downwardly thereon at a front portion and an aperture defined therein at a rear portion. In assembly, the operation part of the fixing member extends through the through hole of the front panel. The drive bracket slides in the chassis from the opening thereof. The hook of the fixing member is received in the aperture of the drive bracket. The fixing part of the fixing member engages with the stop of the drive bracket. Thus, the data storage devices are secured in the drive bracket.

[0009] Other objects, advantages and novel features of the present invention will be drawn from the following detailed description of a preferred embodiment of the present invention with attached drawings.

A flange 151 is bent inwardly from a top of the first side panel 15. The front panel 13 defines an opening 12 therein adjacent to the first side panel 15. A through hole 19 is defined in the front panel 13 adjacent to the opening 12. A support panel 17 is bent perpendicularly rearward from the front panel 13. A flange 171 is bent perpendicularly toward the second side panel 16 from a top of the support panel 17.

[0016] The fixing member 50 made of plastic comprises a generally cuboid-shaped main body 51 mounted on the bottom panel 11 of the chassis 10. A block 57 extends outwardly from a side surface of the main body 51. Two hooks 53 extend rearwardly from a rear portion of the main body and the block 57. Each hook 53 comprises a snake-shaped arm 531 and an arrow-shaped clasp 533 protruding upwardly from an end portion of the arm 531. A guiding slot 55 is defined in the side surface of the main body 51. A fixing portion 60 is formed on a front surface of the main body 51. The fixing portion 60 comprises a vertical fixing part 63, a horizontal operation part 65 extending from a bottom of the fixing part 63, and a rib 67 locating between the fixing part 63 and operation part 65 for strengthening the structure thereof.

[0017] The drive bracket 70 comprises a first mounting wall 73, a first sidewall 78 and a second sidewall (not labeled) extending upwardly from both opposite sides of the first mounting wall 73. The second sidewall comprises a first vertical wall 72, a horizontal second mounting wall 71 and a second vertical wall 79. A plurality of pairs of mounting slots (not labeled) is defined in the first sidewall 78 and the corresponding first vertical wall 72, second vertical wall 79, for mounting the data storage devices therein. Flanges 781, 791 are bent outwardly from the first sidewall 78 and the second vertical wall 79 at a top. A guiding flange 76 is stamped outwardly from a top end of the first vertical wall 72, corresponding to the guiding slot 55 of the fixing member 50. Two Y-shaped apertures 75 are defined in rear portions of the first mounting wall 73 and second mounting wall 71. Each aperture 75 comprises a guiding portion 751 and a locating portion 753. A stop 77 is stamped downwardly from the second mounting wall 71 at a front portion. The stop 77 has a slanting surface (not labeled). In another embodiment, the stop 77 can be formed on the first mounting wall 73. A locking hole may replace the stop 77.
